Boost-Build : |

Hi,
Maybe this is helpful?
boost/test/unit_test.hpp has the following lines:
#if 0
#ifndef BOOST_TEST_NO_AUTO_LINK
#define BOOST_LIB_NAME unix_test_framework
#define BOOST_LIB_DIAGNOSTIC yes
#include <boost/config/auto_link.hpp>
#endif
#endif
(which has been there as long as I can remember - and causes problems
when you download boost and link to boost_unit_test_framework.lib with
vc71 for the first time :)
if I change that to:
#if 1
#if !defined(BOOST_ALL_NO_LIB)
#include <boost/config/auto_link.hpp>
#endif
#endif
the link errror disappears.
However, the next thing that happens is:
boost_prg_exec_monitor.lib(cpp_main.obj) : error LNK2019: unresolved
external symbol "int __cdecl cpp_main(int,char * * const)"
(?cpp_main@@YAHHQAPAD_at_Z) referenced in function "public: virtual int
__thiscall `anonymous namespace'::cpp_main_caller::function(void)"
which I find curious, since I never had to link against that library
where I used to link to 'boost_unit_test_framework.lib' only. (And
still, gcc is not complaining).
Why do I need a cpp_main when I turn of auto_link?
I would be very happy if this is easily explained - and thus fixed :)
Best wishes,
Dirk Griffioen
